A rough idea, for the core races.....
Dwarfblooded (General)
Your bloodline has some dwarven ancestors.
Prerequisite: Humanoid without the Dwarf subtype.
Benefit: You gain the Stonecunning racial trait of a Dwarf, except with a +1 bonus instead of a +2 bonus. Furthermore, you gain a +1 racial bonus on Fortitude saves, and on saves against poison, spells, or spell-like effects, which stacks with itself when appropriate.
Special: This feat may only be taken at your 1st character level.
Dwarven Heritage (General)
You have strong elements of dwarven bloodlines mixed into your own.
Prerequisite: Dwarfblooded.
Benefit: You gain the Stability racial trait of a Dwarf, but at a +2 bonus instead of a +4 bonus. You also gain Darkvision out to a range of 60 feet. However, you suffer a -1 racial penalty on Bluff, Diplomacy, and Gather Information skill checks, as you inherited dwarven gruffness and ego.
Special: This feat may only be taken at your 1st character level.
Elfblooded (General)
Your bloodline has some elven ancestors.
Prerequisite: Humanoid without the Elf subtype.
Benefit: You require only 4 hours of sleep each day, instead of 8 (even for purposes of regaining spells or power points). You receive a +2 racial bonus on saving throws against charm or sleep effects. Furthermore, you receive a +1 racial bonus on Listen and Spot skill checks.
Special: This feat may only be taken at your 1st character level.
Alternative: If half-elves are to be represented by this feat, the feat instead grants a half-elf's trance, immunity to magical sleep spells and effects, a +2 racial bonus on saving throws against Enchantment spells and effects, and a +1 racial bonus on Search checks.
Elven Heritage (General)
You have strong elements of elven bloodlines mixed into your own.
Prerequisite: Elfblooded.
Benefit: You enjoy a +1 racial bonus on Balance and Search skill checks. You also gain a +1 racial bonus on Reflex saving throws, but suffer a -1 racial penalty on Fortitude saving throws. Lastly, you get a +1 bonus on ranged attack rolls made beyond the first range increment.
Special: This feat may only be taken at your 1st character level.
Alternative: If half-elves are to be represented by this feat, the feat instead grants a half-elf's Low-Light Vision, a +1 racial bonus on Listen and Spot checks, a +2 racial bonus on Diplomacy and Gather Information checks, the Elf subtype (but does not remove their Elfblooded feat's benefits), and the Elven language (they learn to speak it, and if not illiterate, to read and write it). However, in that case it also reduces their multiplier for starting skill points from x4 to just x2.
Gnomeblooded (General)
Your bloodline has some gnomish ancestors.
Prerequisite: Humanoid without the Gnome subtype.
Benefit: You gain the Low-Light Vision of a Gnome. You also get a +1 racial bonus on Listen checks and Craft (Alchemy) checks.
Special: This feat may only be taken at your 1st character level.
Gnomish Heritage (General)
You have strong elements of gnomish bloodlines mixed into your own.
Prerequisite: Gnomeblooded.
Benefit: Like a Gnome, you may Speak with Animals once per day as a spell-like ability, as per a 1st-level caster, but only to speak with burrowing mammals. Furthermore, you gain a +1 racial bonus on all Concentration checks, and on saving throws against Illusion spells and effects. Lastly, you receive a +3 racial bonus to your maximum hit points, but suffer a -1 racial penalty on Climb, Jump, and Swim skill checks. You inherited a bit of Gnomish resilience, but also some gnome-like shortness and lean musculature.
Special: This feat may only be taken at your 1st character level.
Halfling-Blooded (General)
Your bloodline has some halfling ancestors.
Prerequisite: Humanoid without the Halfling subtype.
Benefit: You enjoy a +2 racial bonus on Escape Artist, Hide, and Move Silently skill checks. You also gain a +1 racial bonus on Reflex saving throws, but suffer a -1 racial penalty on Strength checks (not Strength-based skill checks), grapple checks, and to your effective Strength modifier for purposes of determining melee damage (before multiplying or halving your Strength bonus if wielding a weapon two-handed or in the off-hand). Your effective Strength score takes a -2 penalty for purposes of carrying capacities. You inherited some of a Halfling's shortness and lithe, lean features.
Special: This feat may only be taken at your 1st character level.
Halfling Heritage (General)
You have strong elements of halfling bloodlines mixed into your own.
Prerequisite: Halfling-Blooded.
Benefit: You enjoy a +1 racial bonus on Fortitude saving throws and Will saving throws. You also gain this racial bonus on Climb, Jump, and Listen skill checks. Furthermore, you enjoy a +1 racial bonus to Initiative checks, but suffer a further -1 racial penalty on grapple checks (for a total of -2 on grapple checks after stacking this with the Halfling-Blooded feat).
Special: This feat may only be taken at your 1st character level.
Orcblooded (General)
Your bloodline has some orcish ancestors.
Prerequisite: Humanoid without the Orc subtype.
Benefit: You gain Darkvision with a range of 30 feet. In addition, you enjoy a +1 racial bonus on grapple checks, Strength checks, and Strength-based skill checks, as you inherit some orcish muscle. You also, however, suffer a -1 racial penalty on Bluff, Craft, Diplomacy, Gather Information, and Knowledge skill checks, as you inherit some orcish ego, animosity, poor memory, and slower than average wits.
Special: This feat may only be taken at your 1st character level.
Alternative: If half-orcs are to be represented by this feat, the feat instead grants a half-orc's Darkvision of 60 feet, and no other bonuses or penalties.
Orcish Heritage (General)
You have strong elements of orcish bloodlines mixed into your own.
Prerequisite: Orcblooded.
Benefit: Your Darkvision from the Orcblooded feat improves to a range of 60 feet. Furthermore, your orcish muscle is improved, yielding a +1 racial bonus to your physical melee damage when dealing such damage in a charge, grapple, or rage (such as during a barbarian rage, or another rage effect). This doesn't stack for charging or grappling during a rage. Your greater burliness is also accompanied by some orcish personality problems and magic deficiencies. You suffer a -1 racial penalty on Charisma checks (not skill checks), and a -2 racial penalty to your effective Intelligence and Charisma scores for purposes of determining bonus spells (if any).
Special: This feat may only be taken at your 1st character level.
Alternative: If half-orcs are to be represented by this feat, the feat instead grants a half-orc's +2 racial adjustment to Strength, -2 racial adjustment to Intelligence, and -2 racial adjustment to Charisma, along with the Orc subtype (but does not remove their Orcblooded feat's benefits) and the Orc language (they learn to speak it, and if not illiterate, to read and write it).
